重磅！商务部、海关总署连发4则公告

Core Viewpoint - The Chinese government has announced export controls on various dual-use items, including superhard materials, rare earth equipment and raw materials, heavy rare earths, lithium batteries, and artificial graphite anode materials, effective from November 8, 2025, to safeguard national security and fulfill international obligations [2][5][34]. Group 1: Export Control on Superhard Materials - Export controls will be implemented on artificial diamond micro-powder with an average particle size less than or equal to 50 μm and artificial diamond single crystals with an average particle size between 50 μm and 500 μm [6]. - Specific characteristics for controlled items include diamond wire saws and diamond grinding wheels with defined parameters such as wire diameter and average particle size [6][8]. Group 2: Export Control on Rare Earth Equipment and Raw Materials - The announcement includes controls on various rare earth production and processing equipment, such as centrifuge extraction devices and ion-type rare earth ore continuous removal equipment with a daily leaching capacity of at least 5000 m³ [7][8]. - Controlled rare earth raw materials include specific types of rare earth ores and flotation agents containing hydroxamic acid or phosphate esters [11][13]. Group 3: Export Control on Heavy Rare Earths - Export controls will be applied to items related to holmium, erbium, thulium, europium, and ytterbium, including metals, alloys, compounds, and various forms of these materials [17][19][21][23][25]. - The controls encompass a wide range of applications, including magnetic materials and crystal materials containing these elements [18][20][22][24][26]. Group 4: Export Control on Lithium Batteries and Graphite Anode Materials - Lithium-ion batteries with a weight energy density of 300 Wh/kg or greater will be subject to export controls, along with equipment used in their manufacturing, such as winding machines and stacking machines [34][35]. - The announcement also includes controls on cathode materials, specifically lithium iron phosphate and nickel-cobalt-manganese hydroxide, as well as artificial graphite anode materials [37][41]. Group 5: Rationale Behind Export Controls - The Chinese government emphasizes that these export controls are in line with international practices to protect national security and interests, and they are not aimed at any specific country or region [42]. - The government is open to facilitating compliant trade and will review legitimate export applications accordingly [42].
